He also favoured longer terms for Pakistan captains like it is in India and Australia.
Predicting on the on-going Indo-Pak series, Waqar said, "It is going to be a very close series. The One-dayers will be very tight games as both the teams are in very good nick and it can go either way.
"However, our bowlers should tighten up their line and length as they gave away too much of width for the Indian batsmen to play their shots in Karachi and once the opposition put on 340 plus runs on the board it was always difficult for Pakistan to chase the target," he said.
On longer terms for Pakistani captain, he said "I feel the Pakistan Cricket Board (PCB) should give at least three-year terms to the captains as they can settle down and knit the team to get good results," the 34-year-old fast bowler said.
The fast bowler, who is in New Delhi as an expert commentator for Sahara TV, cited the examples of Cricket Australia and Board of Control for Cricket in India (BCCI) who have given long terms for their captains to attain success. "Ricky Ponting and Sourav Ganguly are showing good results after being allowed at the helm for a long period. The PCB too should follow this example and give Inzamam-ul-Haq atleast three-years (to prove himself)," he said.
"Previously the captains and the players in Pakistan were changed quite frequently and hence the team suffered," said Waqar, who himself was in charge for a brief period before being sacked after Pakistan's abysmal performance in last year's World Cup.
On the Karachi match, Waqar said: "Credit should be given to both Inzamam and Yousuf Youhana for their magnificent fight back after we had lost two quick wickets. We lost in the end is a different matter but the way the boys fought back was a very good beginning to the series."
"Though Pakistani batsmen played well, the bowlers have to create chances and cut down on the number of no balls and wides and start thinking positively before it is too late," he added. Speaking about his own chances of making a come back into the national team, Waqar, said: "I have been playing club cricket but right now would like to sit back and relax."
"In fact when former Pakistan captains Imran Khan and Wasim Akram were invited by PCB to speak to the young bowlers at the camp before the home series started, I was busy playing for Warwickshire and for North Sydney club before going home to play a couple of domestic matches. I will wait till the current home series is completed before making any future plans," he added.
Asked whether he would be interested to coach Pakistan's young fast bowlers, Waqar said: "Of course, I would love to pass on my experience to youngsters. I feel it is my duty to help up and coming players by sharing my experience."
